Abstract: Aspects of this invention are directed to the substantially improved detection and geolocation accuracy of targets (stationary or moving) by using the coherent data received at multiple airborne sensors. Further aspects are directed to aligning the (unknown) time-delayed and Doppler-shifted signals received at the multiple sensors relative to an arbitrary reference sensor, which depend on the unknown target position. This results in the target position and velocity vectors being simultaneously estimated and the detection peak enhanced by obtaining near coherent gain. Still further aspects are directed to the coherent generalized likelihood ratio test (GLRT) and the minimum variance distortionless response (MVDR) statistic for multistatic radar systems, conditioned on estimation of certain parameters that render the system coherent. Analytical and computer simulation results are presented to show substantially enhanced detection and geolocation of moving targets in clutter.

Abstract: A method, process and system of controlling the transmission of data in a heterogeneous environment having mainframe based storage using FICON and an open system based storage using FC. The invention bridges the heterogeneous environment while maintaining DASD/Disk neutrality. The bridge is a gateway programmed to permit applications residing on the mainframe or open system to map logic paths thereby eliminating or reducing the need to store data prior to transmission. The gateway is able to appear to the first storage device as a standard CTC connection to a mainframe, while appearing to the open system as a number of SCSI tape drives.
